The primary purpose of generating real-time video of realistic-looking talking people is deception. The explicit goal is to make people believe that they're talking to a real person when they aren't.

It's on you to identify the "immense" benefits that outweigh that explicit goal. What are they?

I don't think that's the primary purpose of realistic interactive avatars, any more than deception is the purpose of CGI. Deception requires intent to mislead — if users know they're talking to an avatar, it's not deception no matter how realistic. Just as moviegoers aren't "deceived" by CGI. It's an experience they opt into.

As for benefits: language learning with avatars, scalable corporate training, accessible education for kids, personalized coaching, and certainly entertainment, which has real value too.
